I have a new and clean Windows 2008 Server which I installed Adobe Livecycle ES3 on with Reader Extensions. I did apply the credential file which Adobe supplied, but noticed that the pfx file is from 2009(Could this cause a problem). The server is new and nothing else was installed on it.

When reader extending a form, I get:The document has been changed since it was created and use of extended features is no longer available.

On a new clean server??????We are also on the latest version of everything.(ES3, Adobe Reader X, Acrobat Pro X)
